This thesis investigates the performance of a diffuse wall ventilation concept in terms of contaminant removal effectiveness, and compares it to other concepts based on thermal comfort. Evaluations are made using CFD simulations for three temperature differences and inlet geometries, using an alternative validation approach as lab experiments could not be conducted. It performed well for the requirements set in this thesis, and outperformed most of the other reviewed ventilation concepts regarding operating range based on thermal comfort. It is conclusively found that the diffuse wall is a well functioning and flexible concept for ventilating an office space, provided that the inlet area is placed beneath the contaminant stratification layers, to avoid spreading of contaminants in the occupied zone.
